SPECIFICATION forming part of Letters Patent No. 687,912, dated December3, 1901.

Application tiled September 8, 1900. Serial No. 29,388. (No model.)

T oli whom it may concern:

Be it known that I, ROBERT W. BARKER, a citizen of the United States,residing at No. 147 Tyler street, Paterson, county of Passaic, `andState of New Jersey, have invented certain new and usefulilmprovementsin Heddle- Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersand gures of reference marked thereon, which form a part of thisspecification.

This invention relates to the manufacture of that portion of the heddlesfor sustaining the warp-threads in a loom which comprises an eyelet,calleda mail, through which a warp-thread is adapted to pass, and twoloops of thread'or cord which are strung through the ends of the mailand are adapted the oneto be connected with the warp-actuating means andthe other to carryl the lingo or weight.

The object of the invention is to provide a machine which shall performautomatically the severall operations of feeding the mails, feeding thethread or cord to form the loops, threading the mails onto the threadsor cords, measuring and cutting off the amount of thread needed for eachloop, and, lastly, producing the loops by properly knottingthe threads.

Referring to the accompanying drawings,

Figure 1 is a'front view of the main portionV of the machine. Fig. 2 isan end view in elevation of the right-hand end of the machine, the upperportion thereof being shown as broken away. Fig. 3 shows that port-ionof the machine which is removed in Fig. 2.

Figs. 4, 5and 6 are enlarged top plan views of, respectively, theright-hand portion, the central portion, and the left-hand portion ofthe machine, the arrow-heads in Fig. 1 indieatin g approximately howmuch each of these portions comprises. Fig. 7 is asectional view takenon theline @c in Fig. 1. Fig. 8 illustrates a mechanism for holding theends of the threads or cords which are to form the loops which carry themails. Fig. 9 is a transverse sectional view of the end of a certainfulcrumed arm which is shownin Fig. 1. Fig.

10 illustrates adevice for holding the threads, and thus coacting withsaid arm to doubleor loop the threads af ter having been once looped bysaid arm. Fig. 11 shows a mechanism for maintaining the end of the looplirst formed in each thread separated from the main body of said loopafter the second loop is produced. Fig. l1a is a perspective view ofcertain parts whereby the loops formed in each thread are maintainedseparated from each other. Fig. 12 illustrates a reciprocating hookwhich draws the free ends of each thread through a noose previouslyproduced therein, said noose being adapted to be subsequently drawn upto form a knot. Fig. 13 is an enlarged view showing'the disposition ofthe portions of the thread just previous to forming therein the knot,Vthe noose-forming mechanism being shown. Fig. 14 is a top plan viewshowing the disposit/ions of both threads previously to the tying of theknots therein and also showing the mechanism with which at this timesaid thread engages. Figs. 15 and 16 are enlarged views showing therelative positions of certain parts which coact in forming the nooses inthe threads preliminarily to tying the knots therein. Figs. 17, 18, 19,and 2O are detail views of a mechanism for feeding the mails previouslyto threading them onto the first loops produced in the threads or cords.Fig. 2 t is another detail View of the mechanism for feeding the mailspreviously to threading them onto the loops, the same being a sectionalview on the line o in Fig. 17. Figs. 21,

22, and 23 are detail views of a certain mechanism for threading themails onto the loops of the threads or cords. Fig. 23a shows therelative positions of certainparts of the mechanism for threading themails onto the threads or cords approximately at the time this operationis completed.

Fig. 42, which shows a portion of the edge of the cam shown in Fig. 38.Figs. 36 and 37v riff are a face and edge view, respectively, of of across-piece 1S on which is pivoted a pair a pulley mounted on saidshaft. Fig. 43 is a view of one of the mails, and Fig. 44 is a view ofthat portion of the heddle which is produced by my machine in completeform.

a designates two uprights which are connected and braced at their upperends by a skeleton plateh and near their lower ends by rods c.

d designates a table which is bolted to the plate b, at the right-handend thereof, and in Aone side of which is formed a rectangular openinge. Back of the plate is journaled in the uprights a horizontal shaftf,said shaft being the main shaft of the machine and carrying at one end agear g, in mesh with a pinion 7i, that is journaled upon a stub-shaft1l, said pinion being driven from a pulleyj. The bearing-caps 7c, whichwith the uprights form bearings for said shaft, are shown as removed inFigs. 4 and 6. On this shaft are keyed cams Z m n o p q r s and a pulleyt.

On a support u, which surrnounts the righthand upright, are journaledbobbins o, constituting the thread-supply, the same being controlled byflexible bands w, passing over them, and each band being secured to thesupport at one end and weighted at the other end. There are two bobbins,one being adapted to supply the thread for one loop of each finisheddevice and the other being adapted to provide thread for forming theother loop. From the bobbins each thread extends downwardly to one oftwo weighted slides y, moving on pairs of curved parallel guides z,which are vertically supported in brackets 1 2, projecting from theupright. From the slides the threads extend upwardly over a roller 3,jonrnaled in the end of the table d, and thence through thread-guides 4,their ends being held as hereinafter described.

In the sleeve 5 of a bracket G, (see Figs. 1 and 5,) secured to theplate b, near the center thereof, is journaled a rock-shaft 7, carryingat its rear end a sprocket-wheel 8 and at its forward end an arm 9. Overthe sprocket extends a chain 10, the one end of which is weighted andthe other end of which is coupled to an arm 11, projecting from avertical reciprocating rod 12, havin gits upper end provided with a pairof loops 13, which receive the collars 14 of the cam q. By this meansand also by a guide 15, projecting from the rear rod c, a truelongitudinal reciprocating movement of the rod 12 is insured. Said rod12 carries in the crotch formed between its loops a roller 16, whichbears against the edge of the cam q, (see Figs. 35 and 34,) said rollerbeing normally held in contact therewith by the weight which controlsthe sprocket-chain 10. By the mechanism just described it will be seenthat the arm 9 may be oscillated, swinging over from approximately theposition shown-in Fig. 1 to approximately the position shown in dottedlines in said figure.

Adjacent the thread-guide 4 there is se- 'cured upon the table CZ a post17, in the ends of clips 19, one each side of the post, the upper endsof said clips being adapted to coact with the post to grasp the ends ofthe threads extended vthrough the thread-guides 4, while the lower endsof said clips are normally pressed inwardly by plate-springs 20. Inorder to spread the lower ends of said clips against the action of thesprings, so that the upper ends will be forced inwardly to grasp thethreads, a push-rod 21 is provided, the same being vertically disposedand penetrating the post and the table and being provided near its upperend with a wedge 22, which Works between lugs 23, projecting inwardlyfrom the clips into the post and bearing against said wedge. Thepush-rod has a head 24 on its lower end, between which and the table isdisposed a spiral spring 25, normally acting to force the push -roddownwardly. The head of the push-rod is engaged by one end of a lever26, (shown in Fig. 1,) taking against its under side, said lever beingfulcrumed to the under side of the table and having a vertically-movablerod 27 pivotally connected to its free end. To facilitate the insert-ionof the threads into the clips, their upper ends are provided with guides28, flared away from the post, and in order to prevent the threads fromslipping too far downwardly between the post and the clips a smallcross-piece 29 is soldered to the face of the post, extending across theclips.

Through the base 30 of the post 17 extend two vertical and parallelrevoluble bars 31', which are guided in said base and the table andwhich are swivcled at their lower ends in the head 32 of a rod 33. Thebars 31 are provided with spiral cam-grooves 34, which are engaged bypins 35 (see Figs. 1 and 2) and the pitch of which is sufficient toeffect a quarter-revolution of each bar whenever the pair of bars isreciprocated to its full extent in either direction. The top of each ofthese bars is provided with intersect-ing crosscuts 36 36, one beingdeeper than the other. It will be seen that the action of the bars inturning will bring first the one and then the other of these cross-cutsin alinement with the space between the post and the corresponding guide28.

37 is a hook-bar carrying hooks 3S at its upper end and penetrating thetable, being movable in the extremity of a bracket 39, which issuspended from the table. From said hookbar projects an arm 40, whoseend works in a slot 4l of the bracket, and from the hook-bar projectsanother arm 40,`said last-named arm being pivotally connected to thelower end of the rod 33 between its ends, and also to the rod 27, asshown in Fig. l. In View of the foregoing it will be seen that anyvertical movement of the hook-bar will effect the correspondingmovements of the rods 33 and 27.V The action of the latter is, however,regulated by a set-screw 42, which it carries. (See Figs. 1 and 2.) Thearm 40 is adapted IOO IIO

to be reciprocated by a lever 43, whose forward end is forked, engagingsaid arm 40', while its rear end is provided with a roller 44, whichbears against the periphery of the cam Z. This lever is fulcrumedloosely upon a shaft 45, which is supported at one'end in a bracket 46,secured to the right-hand'upright, and at :its other end in a bracket47, projecting rearwardly from theplate b. A spring 48, connecting thislever and the rod @,inaintains the roller 44 in contact with the cam.

The end of the arm 9 is turned off at right angles, forming a block 49,from which project downwardly pairs of clips, each clip consisting of arigid finger 50 and a pivoted fingerl 51, pins 52 projecting from saidpivoted fingers and being received by inclined slots 53 in a plate 54,constituting the end portion `of a lever 55, that is fulcrumed on thearm 9, being controlled by a spring 56, which connects it with the arm.By shifting the lever 55, as will be hereinafter described, the pivotedfingers are operated so as to open and close the clips. Upon the top ofthe block 49 is -fulcrumed a bell-crank lever 57, one arm of whichcarries a pair of hooks 58. When the arm swings over to the position inwhich itis shown in full lines in Fig. l, these hooks wipe upon theinclined top 59 of the post 17, clearing the tops of the bars 3l andtaking a position against their outer sides, against which they are heldby a spiral spring 60, which actuates the lever 57 in an obvious manner.

6l designates laterally-movable and vertical spacer-bars, which arecarried upon the ends of bell-crank levers 62, projecting upwardlythrough the opening ein the table. Said levers 62 are fulcrumed at 63upon the under side of the table, and the end of one of their free armsis provided with a slot 64, (see Fig. 4,) with which engages a pin 65 ofthe other. The spacer-barsare not perfectly straight, but cach has aslight curvature to theleft, as seen in Fig. 1, near its base. Theirtops are tapered off, as seen in Fig. 11, and each is provided with'anopening 66 and a spur 67 on its outer face, lthe function of which willbe hereinafter described. In order to actuate the bell-crank levers andmove the spacer-bars, operative connection with the drive-shaft iseffected through the medium of the cam fn, a lever 68, fulcrumed on theshaft 45 and carrying a roller 69, engaging said cam, and aconnecting-rod 70, pivotally secured to the adjoining lever 62 on one ofits ends and connected at the other of its ends with the other arm ofthelever 68 by a coup- A spring 72 connects the lever 68 with a bracket 73,projecting from the adjacent end upright to a position opposite the camn.

Assuming that the ends of the threads or cords which have been led intothe machine are held by the clips 19 and that they extend between-said`clips and the thread-guides 4 through the shallow cross-cuts in thebars 31,

if said bars are actuated toimpart to them the .quarter-revolutions, asabove described, the deeper cross-cuts instead of the shallow ones willbe in alinement With the points of i the hooks 58. If now the arrn 9swings over as the points of its hooks 58 move upwardly, they will slipinto the deep cross-cuts beneath the threads or cords in the shallowcross-cuts, and being moved farther upwardly will snap against the clipson the end of said arm, and so the arm will loosely hold said threads.When the arm has completed its movement, or substantially so, a loopwill be formed in each thread, the same extending from the clips 19 tothe clips on the end of said arm. Between these two points, as the armreached the limit of its movement, the two loops thus formed slippedover the beveled ends of outwardly-projecting pins 74 on the upper endsof vertically-disposed levers 75. Each lever 75 is Vfulcrumed upon arest 76, being connected with said. rest by a spiral spring 77, which iscoiled about the fulcruming-pin 78. Each rest has a dovetailedtongue-andgroove connection 79 with a carriage 80, on which said restsare mounted side by side, adjustment being effected by screws 81. Inorder to obtain a more delicate adjustment than is susceptible bythearrangement just referred to, each lever carries in an arm 82,projecting from it, a set-screw 83, which is held against the top of thecarriage by the spring 77. The carriage 80fhas a dovetailed groove 84 inits under face, which receives the correspondingly-shaped arm of abracket 86, projecting from the plate ZJ of the frame. The arm 85extends in alinement with and projects almost into the opening c in thetable. It is provided with a slot 87 under the carriage and throughwhich projects downwardlya pin 88,to which is connected the forward endof a lever 89, controlled bya spring 90, connecting it with the bracket86, and fulcrumed in a support 91, extending rearwardly from the plateb, the rear end of said lever carrying a roller 92, which bears againstone face of the cam p. As shown in Figs. 4 and 32, both faces of the camp are made use of, the one to actuate said lever 89 and the-other toactuate mechanism hereinafter to be described. The reason forreciprocating the carriage 80, and with it the levers 75, by means ofthe lever 89 will be hereinafter set forth. The arm being swung over tothe position shown in dotted lines in Fig. l and in that positionholding the loop which it has formed "in each thread, the mails arethreaded onto said threads. The mechanism for effecting this and theoperation of threading the mails will be now described.

Projecting through the plate and secured upon the same near itsleft-hand end is a frame 93, downwardly-projecting arms 94 of whichserve as bearings for a hollow shaft 95. From said shaft projects an arm96,which is connected with the frame 93 by a spring 97. The `rear end oftheshaft is provided IOO `with another arm 98, which carries a roller99, that is held against the outer one of two concentric camways on oneface of the cam 0'" by the spring 97. The outer end of said shaftcarries an upwardly-extending fork 100. W'ithin the shaft is journaledanother shaft 101, which carries at its outer end a lever 102 and whichat its inner end is provided with an arm 103, carrying a roller 104,which bears against the inner concentric camwayI on the cam r. In orderto keep the roller 104 in contact with the cam, a spring 105 connectsthe lever 102 with a stud 106 on the bracket 86.

Upon the frame 93 is sustained a yoke 107, between the arms of whichthere is supported a ring 108, a horizontal shaft 109 being journaled insaid arms and carrying two hemispheres 110, which, together with saidring, form a spherical hopper. One of them is provided with a fillingdevice 111 and carries a pulley 112, which is connected with the pulleyt on the shaftfby a band 113. In order to manually actuate the shaft andthe hemispheres, the former is provided with a crank 114. One side ofits vertical center the hopper is provided with a tangentially-disposeddischarge-way, the same consisting of a port 115, formed in anenlargement 116 of the ring. Upon a pin 117, projecting from the ring,is fulcrumed a small lever 11S, from which project, the one on one sideand the other on the other side of said enlargement, two bent fingers119, the one being disposed above the other and each having itsextremity adapted to move into one of the two oriiices 120, that extendtransversely through the enlargement, communicating with the port. Thelingers are so arranged that as the lever vibrates said fingers willalternately act to close the port.

120', Fig. 20, designates a removable coverplate forming part of theenlargement, it being of course also penetrated by the orices 120.

121 designates a rest which projects from the supporting portion 122 ofthe ring and which carries at its frontl end a rectangular guide 123, inwhich moves vertically a feeding-block 124, provided with a longitudinalgroove 125, which when closed by a dovetailed slide 126, that is driveninto the block, forms a port which registers with the port in theenlargement of the ring 108. A delicate spring 127 controls the lowerend of this port.

The lower end of the lever 118 is provided with an angular slot 12S, inwhich Works a pin 129, projectingfrom the block 124, the reciprocationof the block being adapted to thus effect the vibration of the lever.The block is reciprocated by means of a rod 130,

which connects a pin 131 on said block with 'by one by the vibratingpins 119 dropping into the port of the block 124, and being held in saidport by the spring 127. The movement of the mails past the fingers isfacilitated by the action of a spring-controlled t hammer 136, which isactuated by pins 137 projecting from one of the hemispheres, the head ofthe hammer being adapted to lightly tap the enlargement 116. The mailsare fed lengthwise through the ports, approximately fitting them. y

From the yoke 107 project two arms 13S 139, in which is sustained areciprocating sleeve 140, having a circumferential groove 141 at itsforward end, into which extend diametrical projections 142 on the fork100. The fork is of course adapted to reciprocate the sleeve. From thefront end of the sleeve projects a pair of hooks 143, which, as shown inFigs. 22 and 23, may assume a vertical or horizontal plane. In thehorizontal plane the spurs of the hooks project upwardly. Upon thesleeve is secured a collar 144, from which projects a pin 145, whichengages an angular slot 146 in a plate 146, secured to the two arms 13S139. Thus as the sleeve is reciprocated it is also oscillated. Withinthe sleeve slides a plunger 147, having a spur 148 at its forward endand provided midway its ends with a reduced portion 149, around which iscoiled a spring 150, which bears against the enlarged rear end of saidplunger and a partition 151 in the sleeve. The plunger is guided by apin 152, working in a slot 153 in the sleeve, it being necessary thatthe spur on the plunger, which is slightly bent for a reason hereinaftershown, maintain constantly the same position relatively to the hooks. Inorder to reciprocate the plunger, it is connected with the lever 102 byan angular :rod 154 engaging its rear end. The movements of the leverand fork 102 and 100 in order to advance the plunger and sleeve are atthe rst synchronous. For a portion of their forward movement the sleeveis so disposed that the hooks are vertical. The sleeve and plungeradvance together until the hooks and spur enter a notch 155 in thebottom of the feeding-block, where they enter the eyelets of the maila', (see Figs. 4 and 23%) taking the same from the feeding-block as thelatter moves upwardly, which now occurs. I-Iaving momentarily stoppedwhile the feeding-block was moving upwardly out of the way, the plungerand sleeve continue to advance, together turning over by the action ofthe pin and angular slot arrangement between said sleeve and the plate146 until the spurs assume the horizontal position. It should beremarked that when the arm 9 swung over IOO IIC?

the free arm of the lever 57, which carries its hooks 58, was engagedbya stationary detent 156, throwing the hooks back out of the way, asshown in dotted lines in Fig. 1. It should also be remarked that eachclip on the arm is provided with a vertical slot 157, formed between itstwo members. Into these vertical slots 157 the hooks 148 are projectedby the advancing sleeve, and when they have entered the slots the arm 9drops slightly still farther, so as to insure the loops of thread orcord which it carries being caught by the hooks, the sleeve at the sametime withdrawing the hooks, so as to clear the clips. The arm now dropsfar enough to bring the points of the clips below the plunger, which nowadvances, itsspur forcing the mail onto the loop of each thread, (whichremains held by the corresponding hook,) one loop passing through eachouter eye of the mail. Having forced the mail a sufficient distance ontothe loops, the plunger is now withdrawn, the sleeve again making aslight advance movement until the spurs enter the Vslots in the clips onthe arm 9, which has meantime returned, and then retracting just as theclips upon the fur ther upward movement of the arm lift the loops odthem. The sleeve and plunger now recede to their initial positions. Ofcourse the action of the arm and of the sleeve and plunger all dependsupon the shapes of the cams which control these parts. As the armcontinues its upward movement its hooks 58 are permitted to snap backagainst the clips, and when `it has swung over to its original positionthe loops still carrying the mail and each being still slipped over theend of one of the clips on the arm are looped over the pins 74, the onebeing upon the one side and the other on the other side of the leverscarrying said pins.

It was above remarked that the spur 148 was slghtly'bent. The object ofthis is to insure the proper securing of the mail upon said spur and thehooks, so that it will not be jarred off by the motion of the machine.

It should be remarked that after the plunger has forced the mail uponthe loops as far as it will go a finger 158, that is fulcrumed upon apin 159 in the bracket 86, is adapted to swing upwardly between theloops, engaging the mail and pushing it still farther onto said loops.The finger 158 carries a small lever 160, having a pin 161, against theunder side of which bears an arm 162, projecting from the shaft 95, andagainst the upper side ofwhichimpinges the end ofalightspring 163,projecting from said arm. By this means the finger is vibrated. As thearm swings over to its initial position the mail drops down upon acurved-wire stop 164, which 'projects upwardly from one of the levers75, the mail ultimately taking a vposition between said stop and anarrow-head or deector 165 upon a support 166,Which is secured upon abracket 167, that is cast integral with a cross-piece 168, that spansthe opening@ in the table and is bolted to the latter.

On the arm 9 is fulcrumed a bell-crank lever 169, one arm of said leverhaving a pinand-slot connection 170 with the lever 55. The free arm ofsaid lever 169 is curved and is adapted to be engaged as the arm 9approaches the limit of its return movement by a roller 171 on an arm172, projecting from a rock-shaft178, which is journaled in brackets 174and 175, respectively, mounted upon the shaft 45 and the table. Therock-shaft 178 also carries another arm 176, having a roller 177, whichbears against the camway of the cam o, being held in contact therewithby a spiral spring 178, coiled about the shaft and engaging the same andthe bracket 174. The rock-shaft being actuated, the lever 169 works thelever 55 and opens the pairs of clips 19, around which the threads arelooped. The opening of the clips of course effects thewideningoftheloops Itshould be remarked that whereas the spacer-barswere apart when the arm swung over when it swings back said spacer-bars61 come together again. 'lhusin the former case the threads were laid.between them, whereas in the latter case they are passed outside ofthem. The clips now dropping to their extreme lowest position (the loopin each thread extending from the corresponding clip 19, which holds itsextremity while the body portion ofthe thread itself lies in the guide28, back inside of the spacer-bar, outside an arrow-head or deflector179 and the other arrowhead 165, around the pin 74, and forward againoutside of said arrow-heads and the spacer-bar to the corresponding clipon the arm 9) grasp the threads leading from the clips 19.

180 and 181 designate two knives which are pivoted upon a loose link182, supported upon the table, the knives constituting shears. The endsof these knives have slotted arms 183 disposed at an angle to the knivesthemselves, the slots in said arms receiving a pin 184 on a'lever 185,that is pivotally joined to another lever 186 on the shaft 45 by aconnecting-rod 187. This last-named lever is normally held rearwardly bya spring 188, connecting it with the bracket 78. It carries a roller189, which is held against the cam m by said spring. Mounted upon thetable in front of the link 182 is an adjustable stop 190, against whichsaid link is adapted to impinge as the cam advances the shears throughthe intermediate mechanism, so that said shears in the limit of theirforward movement will be caused to close. Now referring to Figs. 15 and16 it will be seen that after the clips have grasped the threads in themanner already described (still holding their loops) the knife 180 ofthe shears, which lat-ter has been caused to advance, as abovedescribed, wiping against the clips forces the loop off the latter. Justbefore the shears close to cut the threads the clips 19 open, permittingthe body IOO IIO

portion of each thread which they hold to drop into them, immediatelyclosing to grasp the same. The shears thereupon complete their movement,cutting the threads. At this point the clips on the arm 9 are `graspingthe loose ends of the cut-off portions of the threads,

said loose ends constituting the end portions of nooses the bights ofwhich extend around the spacer-bars 61 and the pins 74E of the levers75, while a small piece of the original extremity ofthe thread and thenew end formed therein remains held b v each clip 19. (See Fig. 16.) Assoon as the nooses are formed the carriage 80 moves backward under theactuation of the lever 89, which the cam p operates, as alreadydescribed, the elastic mounting of the levers 75 preventing any unduepull upon the nooses. It should be remarked at this point that at themoving back of the carriage the nooses are drawn up taut, extendingaround the spacer-bars 61 in line with the orifices 66 formed therein,beingheld there by the spurs 67. It should be also remarked Lhatinasmuch as in forming the nooses each thread is doubled twice, first asthe arm 9 swings over and then as said arm swings back, when in theclaims such expressions as auxiliary looping member, auxiliary loopingdevice,7 and the like are used reference is made to means which inengaging the thread after the first doubling coacts with the arm toproduce the second doubling as said arm swings over to its initialposition. In the embodiment of my invention illustrated such auxiliarymembers or devices are the pins on the levers 75. Likewise theexpression thread-looping member (or device, dac.) proper employed inthe claims of course has reference to means which draws the threadtoward the mail-threading mechanism and which in so doing produces thefirst doubling. In the said accompanying illustration of the inventionsuch means is the arm 9 and its accessory parts. The operation of tyingthe knot in the two nooses now succeeds.

In the hook-bar 37 is formed a longitudinal groove 191, in which works arod 192, carrying at its upper end an elastic fork 193,whose normaltendency is to assume a position with its forked upper end in proximityto the spacer-bars 61. The upper end of this fork is guided in a bracket194:, which is secured to the edge of the table in the recess e. Fromsaid rod project two lugs 195, between which projects the end of a lever196, which is fulcrumed upon the shaft 45 and engages by means of aroller 197, mounted on its rear end, the periphery of the cam o. Theroller is normally held in contact with said cam by a spring 198, whichconnects the lever with the rod c. By the mechanism just described afterthe nooses are formed the fork 193 is elevated and engages that portionof each thread which is between the nooses and the clips on the arm.

In the bracket 47 and in another bracket 199, which is suspended fromthe table, is journaled a rock-shaft 200, carrying a collar 201, fixedon said shaft, said collar and the bracket 47 being connected by aspring 202, normally acting upon the shaft to turn the same. Said shaftcarries at its rear end an arm 203, provided with a roller 204:, whichis held against the camway on the cam p opposite to that against whichthe roller 92 bears by the spring'202. At its forward end said rock-.shaft carries another arm 205, whose slotted upper end engages across-piece 206, in which are swiveled the rear ends of reciprocatingtwister-bars 207, which penetrate an integral block 208 on the bracket167, said bars being provided with cam-grooves 209, with which suitablekeys in the form of screws 209' and mounted in the 'block 208 engage, soas to turn each bar a quarter-revolution in each of its longitudinalmovements. 209 designates an auxiliary supporting-bracket for thesebars. In its rearmost position each bar 207 is back of the correspondingspacer-bar 61, and as its forward end, which is notched, as shown inFig. 13, advances through the orifice in said spacer-bar it engages thenoose, and thereupon effects a twist in the latter as said .bar turnsover. (See Fig. 13.) The end of each noose (which the bar engages) isnow advanced by the bar past the fork'193, a portion thereof being laidunder that part of the threads which is intermediate the clips on thearm 9 and said fork. At this time the hooks 38, heretofore described,are elevated, engage the ends of the thread, as seen in Fig.

13, and immediately dropping draw said ends down through the small'locpformed by twisting each noose. Thereupon the rock-shaft 173 is permittedby its actuating-cam to withdraw the roller 171 from contact with thelever 169, whereupon the mechanism intermediate said lever and the clipson the arm 9 effects the opening of said clips to release the ends ofthe nooses. The tension on the nooses being constantly maintained by theelastically-mounted levers 75, as the bars 207 retract they untwist thenooses, the knot being meantime drawn tight. The drawing up of the knotsbeing effected by virtue of the tension which the elastic pin-carryinglevers 75 exert, as soon as the fork 193 releases the thread, which nowoccurs, the fork retracts under the actuation of its controllingmechanism. As the ends of the bar 207 have receded through IIO thespacer-bars the nooses are of course re- Y tension on the threads as thearm 9 swings over and back, I have yprovided a fork 210, carried by alever211, which is fulcrumed upon a shaft 212, and an arm 213 of whichhas a slot-and-pin connection 214 with a reciproeating rod 215, that iscontrolled by a spring 216 and carries a roller 217, which bears againstthe cam s. In'order to guide the rod 215, its upper end has a fork 21S,which engages a collar 219 of said cam.

The mechanism shown supported upon the right-hand end of the plate b issimply for indicating the number of couplings that have been completed.Upon astud 220, projecting from said plate, is journaled a ratchet-wheel221, carrying a pin 222, which is adapted to engage an elastic hammer223, secured upon said plate and arranged to sound a gong 224, alsosecured upon the plate. The ratchetwheel is actuated by aspring-actuated pawl 225, pivoted upon a lever 226, which is fulcrumedupon the stud 220, said lever being connected with another lever 227 byarod 228. The lever 227 is normally held against a stop 229 by a spring230 connecting it with the upright, and it is adapted to be engaged by apin 231 on the gear g. Thus every time the gear revolves theratchet-wheel is advanced one notch, and each time said ratchetcompletes a full revolution the gong is sounded. A stationary pointer232 on the stud 220 serves, with a dial 233, which is provided on theface of the ratchet-wheel, as an auxiliaryindieating mechanism.

I-Iaving thus fully described. my invention, what I claim as new, anddesire to secure by Letters Patent, is-
